Numbers were not disclosed. An OKC blog suspects more than $80M for 5 years, as that is what Yahoo had reported yesterday.

Russell Westbrook has been locked up.

The Oklahoma City Thunder has signed its All-Star point guard to a multi-year contract extension, the team announced Thursday.

Details of the deal were not released, per team policy. But according to Yahoo! Sports, which first reported the deal, Westbrook will earn more than $80 million over five years, the maximum number of years for which he could have re-signed.

The deal, which will go into effect next season, would keep Westbrook in Oklahoma City through the 2016-17 season.

“We are thrilled to solidify Russell’s future with the Thunder,” said team general manager Sam Presti in a statement. “Since we arrived in Oklahoma City, Russell’s work ethic, persistence, character and involvement in our community have helped us establish the standards that we are committed to on a day-to-day basis. He is a valued member of our organization and we look forward to his continued contributions on and off the floor.”

Westbrook has averaged 17.9 points, 4.8 rebounds, seven assists and 1.5 steals in 261 career games since being drafted fourth overall out of UCLA in 2008. He was selected by coaches as an NBA All-Star for the first time last season and was also an All-NBA Second Team selection following the 2010-11 season.
